Stop Brake Fluid Boil: Summer Mountain Descents

Cost Savings

Checklist Tasks

• Test brake fluid moisture with a digital tester; ensure it stays below 2%.
• Check master cylinder for dark or cloudy fluid, replace if degraded.
• Flush brake fluid if over two years old or moisture is present.
• Inspect caliper and wheel cylinder seals for leaks or seepage.
• Check brake hoses for swelling, cracks, or brittleness.
• Clean caliper vents and dust boots to prevent heat buildup.
• Inspect rotors for blue tint or cracks from past overheating.
• Ensure brake pads have enough thickness for heat absorption.
• Bleed brake lines fully to remove air bubbles that can cause fade.
• Ensure brake fluid cap seal is intact to block humidity entry.
• Check parking brake release to avoid dragging and heat buildup.
• Plan descent routes with pull-offs for brake cooling if necessary.
